70 r/t

New here, but not to the 1st gen Challenger. Owned a sweet '70 S/E, but she's long gone now. I do have a line on a '70 R/T (383, auto). The body is good, minimal rust, has original sport wheels, interior should clean up, but............. needs engine, trans is questionable. The only mod(s) I can see is that the battery was moved to the trunk. My dilemma is what to offer for it in the present condition. Any and all credible comments are more than welcome! Thanks, T
